Sempervivum tectorum is better known as?

Sempervivum tectorum is commonly known as "Hens and Chicks." This name derives from the plant's unique growth habit, where the larger parent rosette (the "hen") produces smaller rosettes (the "chicks") that cluster around it. This characteristic makes it a popular choice in gardens and rockeries, where it adds visual interest through its compact growth and ability to thrive in various conditions. Additionally, "Hens and Chicks" is often used to describe other similar succulents, but Sempervivum tectorum specifically is recognized for its cold hardiness and low maintenance requirements, making it well-suited for many landscapes.

The other options do not relate to Sempervivum tectorum in any way: Dwarf Pampas Grass is a type of ornamental grass, Lungwort is a flowering perennial known for its spotted leaves and shade tolerance, and Golden Variegated Sweet Flag is an aquatic plant with distinctive variegated foliage. Each of these options represents a different category of plants, highlighting the uniqueness of "Hens and Chicks" within the context of horticulture.
